To ZZ whom t may concern.:

Be it known that I?, CII-Annes Arens, a citizen of the United States, residing at Salem, in the county of' Salem and State-of New- .Iersey, have invented. certaiirnew and useful Improvements in: Canning Machinery, of whichl the following is. aspecieation.

@ne of the ever present problems inthe canning industry isprovisionxof adequate means `for insuring.'completer discharge ofthe `granular material; The tendency of viscous granular material tov adhere-'to the hopper presentsy an ever present*problemv in thev canning art and many attempts have been made to solve this problem. I have discovered that by imparting' a1 continuous axial rotation tofthe hopper so that the material islfed against l a constantly movingrv inclined surface which induces a downwardly directed spiral movement of the material, the tendency vto adhesion is4 effectively' overcome. One ob ject of my invention istofprovide simple and efficient means for imparting such continuous rotation and securing. such spiral movement of the'material f It the rotating hoppen feeds the material intofa stationary hopper or.` tunnel which .delivers it tothe; cans, it is practically essential that meansjbe provided for guarding against adhesion of the material tothe walls of the stationary hopper@a and another object of; my invention is to provide suehmeans.

If.k the rotating hopper isrtoffuncton properly with adjustable measuring units itis essential'that the-hopper and one part of the measuring unitsy be: 'adjustable relatively to the other part, andI it is another` obj ecto fg my invention tor pro-vde tor suoh adjustment.

These objects and otheradvantageousends, which wllfbe; described hereinater, I7 attain in -t-he -following-mannerL reference b eing had tothe aceompanyingdrawings in Wliioh- Figure 1 is' a central vertical section through the 1101112.91'- Aand? turret of a ycanning machine,

Fgure a horizontal Section op lilie- 2&2 of Figure 1, and

Figure 3 a horizontalseotion on line 3--3 of Figure' 1.

The numeral lindioates the hopper,i2fthe stationaryhopper Qrfunnel leading'rom the hopper to-the measuring units, 3 the measuring vwheel, 4f aveltoal shaft whichsupports the hopper parafair'uigY wheel and-imparts rotation thereto and 5 the hed plate upon which the measuring wheel rotates. The measuring w-heel consists otwo telescoping parts 6 and 7. In the Jform shown, part 6 is splinedl to the shaft and rests upon the hed platev and part 7 extends upwardly forming a' boss 8 emhraeingthe upper end of the shaft and carrying a gear wheel 9 which meshesr with an internal gearl '10 fixed to the hopper and rotatable in? a' bearingll carried by a part of the frame whichiis fixed aga-inst rotation. A hood 12 cofvers'gear wheel 9 and mergesiinto a hand lliixed toy a part of the-iframe which is alsoXed against' rota tion. The band embraces tlielower edgev of the hopper, extends within gear 10 and guards it against access of the materialI fed through the hopper. Gear 110y is provided with an external annular shoulder 15y which is embraced by clamps 16 detachahly con-y nectedV with bearing 1'1, or? some part of the frame fixed against rota-tion,- and` serv-lng to yhold the-hopperl and gear 1f1y against unintentional upward displacement.

In order toprovide'against adhesion of the material to the wallsvo the stationary hopper 2, through which `the material passes from the hopper to the' measuring unit-s, I provide a liquid inlet 17 communicating with an annular channel 18 provided with perfor-ations 19 and preferably' fedby a ilexlibletube-QO.v By this'means the walls oiy the chute are continuously lubricated and danger ofy the adhesion is avoided.

In order toenable theV hopper rot-ating mechanism 'to function in connection with adjustable measuring units,I provide a rod `21 extending. within the hopper, taking through boss' 8 andy having at its lower yend a threaded part 22 taking into a looreinsliaiftV In use I Lind that the/granular material,

Cil

instead of maintaining a high level in part of the hopper and feeding from the other part as is usual, maintains a. level upper sur-,U

face and feeds uniformly without adhering to the wall. The rod 2l, being stationary and in the path of travelr of the material serves as a stirrer and neutralizes any tendency of the material to cohere in objectionable masses.

lVhile I have described my invention as 'taking a particular forni, it will be understood that the various parts may be changed without departing from the spirit thereof, and `hence I do not limit myself to the precise construction set forth, but consider that `-I am at liberty to make such lchanges and alterations as fairly come within the scope'of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is l'. In a can filling machine, a feed hopper; a gear carried thereby; a power driven shaft; a measuring unit secured to the shaft v and rotatable therewith, the measuring unit consisting of telescoping parts adapted to receive material from the hopper, and a gear carried by one of the telescoping parts and meshing with the gear on the hopper.

2. In a can filling machine, a feed hopper; a gear carried thereby; a power driven shaft; a measuring unit secured to the shaft v and rotatable therewith, the-measuring unit consisting of telescoping parts adapted to receive material from the hopper; a gear Y cai'ried by one of the telescopingvparts and meshing with the gear on the hopper, and means for raising or lowering the hopper and one of the telescopingparts.

4. The combination in a can filling machine of a hopper; a gear cariied thereby; a power driven shaft; a gear carried by the shaft meshing with the gear on the hopper, and a stationary rod extending through and 1 supporting the hopper and threaded into the shaft whereby the hopper may be raised or lowered relatively to the bed.

5. In a can filling machine, a rotatable hopper; a rotatable measuring unit having telescoping parts and arranged to receive material from the hopper; a power driven shaft; a gear carried thereby; a gear carried by the hopper meshing with the gear carried by the shaft, and a rod extending through the hopperfand threaded into the shaft whereby the hopper and one of the telescoping parts may be raised orlowered relatively to the bed.

6. In a can filling machine, a. rotatable hopper; a rotatable measuring unit having telescoping parts; a stationary hopper arranged to receive material from the rotatable hopper and deliver it to the measuring unit; a power driven shaft; a gear carried thereby; a gear carried by the rotatable hopper meshing with the gear carried by the shaft, and a rodeXtending through the rotatable hopper and threaded into the shaft whereby the rotatable hopper, the stationary hopper and one of the telescoping parts may be raised or lowered relatively to the bed.

7. In a can filling machine, a rotatable hopper; a rotatable measuring unit' having telescoping parts; a` stationary hopper arranged to receive material from the rotatable hopper and deliver it to the measuring unit; a power driven shaft; a gear carried thereby; a gear carriedV by the rotatable hopper meshing with the gear carried by the shaft, and a rod extending through the rotatable hopperthreaded into the shaft and carrying one of the telescoping parts whereby the rotatable hopper, the stationary hopper and one of the telescoping parts may be raised or lowered relatively to the bed.
